Specification of Letters Patent.

Patented May 4, 1909.

Application filed March 14, 1968. Serial No. 420,998.

To all whom it may concern:

Be it known that I, OLE G. SYVERTSEN, a citizen of the United States, and a resident of Taunton; in the county of Bristol and State of Massachusetts, haveinvented a new and Improved Water-Heater, of which the followin is a full, clear, and exact description.

his invention is an improved water heater for domestic purposes, more especially constructed to be used in connection with the boiler of a steam heating system and replace or augment the water heating apparatus of the kitchen range.

With this in, view I provide a heating chamber preferably consistingl of a cylindrical body having ex anded ads secured at opposite ends, a co within the chamber, and a common inlet and outlet to and from the chamber, for the circulation of the heating fluid. At the points where the return and su ply pipes of the coil pass into the head, i preferably provide outwardly-projecting nipples surrounding the pipe having packing nuts, and forming in connection with spaces in com munication with the chem er.

Reference is to be had to the accompany ing drawings forming a part of this specification, in which similar characters of reference 80 indicate corresponding parts in all the views.

Figure 1 is a diagrammatic view showing my improved water-heater in connection with the usual domestic heating apparatus; Fig. 2 is.a central vertical section through my improved water heater; Fig. 3 is a crossand Fig. 4 is a view similar to Fig. 1, showing the heater located at a different point.

The invention essentially consists of a section of the same on the line 3-3 of Fig 2;

to heating chamber, and a water coil within the chamber, the chamber preferably consisting of a cylindrical body 5, having expanded heads .6 and 6 secured at opposite ends,,the head 6 having a common inlet and outlet connection 7 for theintroduction and discharge of the heating fluid, and the head 6 having a vent valve 8. The water coil preferably comprisesa suppl pipe 9 and a return pipe 10 which pass t rough the front of the head 6 and are connected to ether adja- OW 11, the Patent:

cent to the head 6 by a return e and c the walls oft e chamber and from each other 1 to admit of the free circulation of the heating agent about them. Where the pipes of the coil pass through the head 6, outwardlyproj ectin ni ples 12 are threaded into the latter lose y fit the pipe only at their outer ends, Where each is provided with a packing nut 13, containing the packing 14. The inner portions of the bores of the nipples are increased in diameter to provide in connection with the pipes, annular heatin spaces in communication with the heating 0 amber. This construction of the stuiiing-boxes about the ipes, increases the heatin surface as much as if the cylindrical bo y 5 of the chamber were increased to the same extent, without the disadvantages incident thereto. The single connection with the heating chamber for both the inlet and outlet of the heating fluid,. I have found in practiceto ber throu h the stuffing boxes, and in this way any eating area within certain limits be obtained.

In Fig. 1 I have shown the application of the heater to an ordinary form of domestic heating apparatus, in which the connection 7 Y is piped to the boiler 15 of the steam heating s stem, and the sup ly and return pipes of the coil connect wit the tank through the pipes leading to and from the water back of the kitchen range.

The application of the heater in Fig. 4 is in all rtspects the same as that shown in Fig. 1, except that the heater islocated in the cellar instead of in the kitchen, which in some cases is found preferable.

Having thus described my invention, I claim as new and desire to secure by Letters g f I 920,687
